The goal of this clinical trial is to find out if Vibrotactile Stimulation (VTS) can help improve mobility and reduce spasticity (muscle stiffness) in people with lower limb spasticity. The study will also look at how VTS affects walking speed. The main questions it aims to answer are:
* Which areas of the body are the best for applying VTS? * Does VTS help improve walking speed in people with lower limb spasticity?
Participants will:
* Receive 15 minutes of VTS treatment on different parts of the body * Use the VTS device for 60 minutes during supervised lab sessions and at home (at rest and while walking) * Complete a daily log of how much time the device was used for and note any issues or difficulties the participant experience * Complete assessments after the treatment to measure change in mobility * Complete surveys about how comfortable the device is to use
